Chapter 2: Board Installation

Installation

You are now ready to install your motherboard. The mounting hole pattern of the Tomcat i845GV

matches the FlexATX system board specifications. Your chassis should support a standard

FlexATX motherboard form factor.

How to install our products right…. the first time!

The first thing you should do is read this user’s manual. It contains important information that will

make configuration and setup much easier. Here are some precautions you should take when

installing your motherboard:

(1) Ground yourself properly before removing your motherboard from the antistatic bag.

Unplug the power from your computer power supply and then touch a safely grounded

object to release static charge (i.e. power supply case). For the safest conditions, TYAN

recommends wearing a static safety wrist strap.

(2) Hold the motherboard by its edges and do not touch the bottom of the board, or flex the

board in any way.

(3) Avoid touching the motherboard components, IC chips, connectors, memory modules,

and leads.

(4) Place the motherboard on a grounded antistatic surface or on the antistatic bag that the

board was shipped in.

(5) Inspect the board for damage.

The following pages include details on how to install your motherboard into your chassis, as well

as installing the processor, memory, disk drives and cables.

NOTE DO NOT APPLY POWER TO THE BOARD IF IT HAS BEEN DAMAGED

2.9 – Mounting the Motherboard

Before installing your motherboard, make sure your chassis has the necessary motherboard

support studs installed. These studs are usually metal and are gold in color. Usually, the chassis

manufacturer will pre-install the support studs. If you’re unsure of stud placement, simply lay the

motherboard inside the chassis and align the screw holes of the motherboard to the studs inside

the case. If there are any studs missing, you will know right away since the motherboard will not

be able to be securely installed.

Some chassis’ include plastic studs instead of metal. Although the plastic studs are usable, TYAN

recommends using metal studs with screws that will fasten the motherboard more securely

in place.

Below is a chart detailing what the most common motherboard studs look like and how they

should be installed.

11

http://www.TYAN.com

TIP: Use metal studs if possible, as they hold the motherboard into place more securely than

plastic standoffs.

12

http://www.TYAN.com

2.10 – Installing the Memory

Before attempting to install any memory, make sure that the memory you have is compatible with

the motherboard as well as the processor. For example, while PC1600 DDR modules are

compatible with all DDR based motherboards, they will not work if you are required to run the

motherboard and processor buses at 133MHz. For this, PC2100 DDR modules are required.

Critically important is whether you’re using the recommended memory for the current board you

have. For this information, please check TYAN’s web site at: www.TYAN.com

.

The following diagram shows the types of RAM modules you may encounter.

Use only 184-pin unbuffered non-ECC memory for S2198.

Unbuffered

Non-ECC

= 8 Chips

Unbuffered

ECC

= 9 Chips

Note: The Tomcat i845GV has two DIMM sockets, which supports a maximum of four banks of

DDR memory (only supports 64 Mb, 128 Mb, 256 Mb, and 512 Mb technologies for

x8 and x16 devices.)

13

http://www.TYAN.com

2.11 – Memory Installation Procedure

When you install the memory modules, make sure the module aligns properly with the memory

slot. The modules are keyed to ensure that it is inserted only one way. The method of installing

memory modules are detailed by the following diagrams.

Once the memory modules are firmly seated in the slot, two latches on either side will close and

secure the module into the slot. Sometimes you may need to close the latches yourself.

To remove the memory module, simply push the latches outwards until the memory module pops

up. Then simply remove the module.

NOTE

Due to the PCI v2.2 specifications, you MUST unplug the power connector to the

motherboard before performing system hardware changes to avoid having your

motherboard boot-up automatically.

14

http://www.TYAN.com

2.12 – Installing the Processor and Heatsink

Your brand new Tomcat i845GV supports the latest processor technologies from Intel. Check

TYAN’s website for latest processor support:

http://www.TYAN.com

The following diagrams will detail how to install your processor:

The processor you choose to use may not look exactly like the one pictured above, nor will the

socket look exactly the same. For example, your processor may appear to be in a different color

and have different markings on it. The diagram is provided as a visual guide to help you install the

processor.

1. Lift the lever on the socket until it is approximately 90

o

or as far back as possible

to the socket.

2. Align the processor with the socket. There are keys underneath the processor just like

on memory modules to ensure that they insert the correct way.

3. Seat the processor firmly into the socket by gently pressing down until the processor

sits flush with the socket.

4. Place the socket lever back down until it snaps into place.

5. Your processor is installed.

Take care when installing Pentium 4 processors as they have very fragile connector pins

below the processor and can bend and break if inserted improperly.

Heatsink Installation

After you are done installing the processor, you should proceed to installing the heatsink. The

heatsink will ensure that the processor does not overheat, and will continue to operate at

maximum performance. An overheated processor is also dangerous to the long-term reliability of

the motherboard.

Because there are many different types of heatsinks available from many different manufacturers,

many have their own method of installation. For the safest method of installation and information

on choosing the appropriate heatsink, please refer to TYAN’s website: http://www.TYAN.com

.

15

http://www.TYAN.com

Finishing Installing the Heatsink

After you finish installing the heatsink onto the processor and socket, attach the end wire of the

fan (which should already be attached to the heatsink) to the motherboard. The following diagram

illustrates how to connect fans onto the motherboard.

After you’re finished installing all the fans you can connect your drives (hard drives, CD-ROM

drives, etc.) to your motherboard.

2.13 – Attaching Drive Cables

Attaching IDE cables to your drives is simple because they only go in one way. TYAN

motherboards have two on-board IDE channels for you to use, each supporting two drives. There

is a white and a black IDE connector on your motherboard. The black connector is the Primary

IDE channel and the white connector is the Secondary IDE channel.

Attaching IDE cables to the IDE connectors is illustrated below:

Simply plug in the BLUE END of the IDE cable into the motherboard IDE connector, and the other

ends into the drive(s). Each standard IDE cable has three connectors, two being close to each

other. The BLUE connector that is far on its own is the end that plugs into the motherboard

whereas the other two connectors are used to connect to drives.

TIP: Pin 1 on the IDE cable (usually denoted by a colored wire) faces the drive’s power

connector.

16

http://www.TYAN.com

Serial ATA

Attaching Serial ATA cables to the Serial ATA connectors are illustrated below:

Plug in one end of the Serial ATA cable into the motherboard Serial ATA connector,

and the other end into the drive. Each standard Serial ATA cable has two

connectors, one at each end. Connectors are the same on both ends.

NOTE

Before continuing onto Connecting External Devices, make sure everything is

properly connected. Things like jumpers and case wiring are the most common

causes of troubleshooting frustrations, both for the end-user and for any

company doing technical support.

17

http://www.TYAN.com

2.14 –

Installing Add-In Cards

Before installing add-in cards, it’s good to be aware if they’re fully compatible with your

motherboard. For this reason, we’ve provided a chart, listing the most common slots that may

appear on your motherboard. Not all the slots in this diagram will be on the same board though,

but there will be combinations. See below for the way the slots look and what each one means.

Simply find the appropriate slot for your expansion card and insert the card in firmly. Do not force

any expansion cards (or anything else) into any slots if they refuse to go in. It’s better to try

another slot or return the faulty card rather than damaging both the motherboard and the card.

TIP: It’s good practice to spread out cards as far apart from each other as possible if you can. This

gives more breathing room and sensitive electronics will cool better and perform more reliably.

NOTE

YOU MUST unplug the power connector to the motherboard before performing

system hardware changes, to avoid having your motherboard boot-up

automatically, due to the PCI v2.2 spec.

18

http://www.TYAN.com

2.15 – Connecting External Devices

The standard devices you should expect to plug into the motherboard are keyboards, mice, and

printer cables. The following diagram will detail the ATX port stack for the following board:

S2198 Tomcat i845GV

TIP: While the ports have been created to accept connectors in only one direction, make sure to

be careful when inserting connectors. At times, attaching connectors in the incorrect orientation

can damage, bend and or break the pins.

2.17 – Installing the Power Supply

There are two power connectors on your Tomcat i845GV. By default, the Tomcat i845GV requires

that you have an ATX12V power supply that has a 20-pin and a 4-pin power connector. Do not

use any other type of power supply.

1. Disconnect power supply from electrical outlet

2. Connect ATX12V 4-pin power connector(J11)

3. Connect ATX12V 20-pin power connector(J18)

4. Connect power cable to power supply to power outlet

Make sure you have connected BOTH the 20-pin and 4-pin connectors before attempting to

apply power to the board.

2.18 – Finishing Up

Congratulations on making it this far! You’re finished setting up the hardware aspect of your

computer. Before closing up your chassis, make sure that all cables and wires are connected

properly, especially IDE cables and most importantly, jumpers. You may have difficulty powering

on your system if the motherboard jumpers are not set correctly.

In the rare circumstance that you have experienced difficulty, even though the instructions herein

were followed, you can find help by asking your vendor for assistance. If they are not available for

assistance, please find setup information and documentation online at our website or by calling

your vendor’s support line.

Chapter 3: BIOS Setup

Installation

The BIOS is the basic input/output system, the firmware on the motherboard that enables your

hardware to interface with your software. This chapter describes different settings for the BIOS

that can be used to configure your system.

The BIOS section of this manual is subject to change without notice and is provided for reference

purposes only. The settings and configurations of the BIOS are current at the time of print, and

therefore may not match exactly what is displayed on screen.

This section describes the BIOS setup program. The setup program lets you modify basic

configuration settings. The settings are then stored in a dedicated, battery-backed memory (called

NVRAM) that retains the information when the power is turned off.

This motherboard’s BIOS is a customized version of the industry-standard BIOS for IBM PC

compatible personal computers. The BIOS provides critical, low-level support for the system’s

central processing unit (CPU), memory, and I/O subsystems.

This BIOS has been customized by adding important features such as virus and password

protection, power management, and chipset “tuning” features that control the system. This section

will guide you through the process of configuring the BIOS for your system setup.

Starting Setup

The BIOS is immediately activated when you turn on the computer. The BIOS reads system

configuration in CMOS RAM and begins the process of checking out the system and configuring it

through the Power-On-Self-Test (POST).

When these preliminary tests are completed, the BIOS searches for an operating system on one

of the system’s data storage devices (hard drive, CD-ROM, etc). If one is found, the BIOS will

launch that operating system and hand control over to it. You can enter the BIOS setup by

pressing the [Delete] key when the machine boots up and begins to show the memory count.

NOTE

THE FOLLOWING SECTION DETAILS MOST IF NOT ALL OF THIS BOARD’S

BIOS FEATURES.

HOWEVER, YOUR ACTUAL BIOS SETUP MAY NOT BE EXACTLY AS THE

ONE DETAILED IN THIS MANUAL.

PLEASE REFER TO THE TYAN WEBSITE FOR UP TO DATE FEATURES

CONCERNING BIOS AND OTHER DATA.
